In a redundant network design, what does 'automatic failover' mean?

The network detects a failure and switches to a backup component without human intervention

The network shuts down all traffic until the failed component is replaced

Traffic is rerouted to a different data center only during scheduled maintenance

Traffic is manually rerouted by an administrator when a failure occurs

A virtualization administrator is configuring a cluster of two hypervisors. The administrator wants to ensure that if one hypervisor fails, the virtual machines can be restarted on the other hypervisor and remain reachable at the same IP address. What should be configured?

Link aggregation on the virtual switches

A floating IP address that moves with the VM during failover

What is the primary purpose of Multipath I/O (MPIO)?

To provide multiple physical paths between a server and storage for redundancy and load balancing

To combine multiple storage devices into a single logical volume

To increase the storage capacity of a server

To encrypt data stored on the storage array

How does MPIO help maintain connectivity to storage?

By using a single, highly reliable path to the storage

By storing a copy of the data on the server's local disk

By compressing data to reduce the number of paths needed

By automatically switching to an alternate path if the primary path fails

A server has two 1 Gbps NICs connected to two different switches. The administrator wants to configure NIC teaming to provide both failover and load balancing. The switches are not configured for link aggregation. What is the best teaming mode to use?

Switch-independent teaming with address hash load balancing

Link aggregation (LACP) teaming
